macaw filed Januar 22, 1913. Serial in. 743,431.

Apparatus for Tanks, of which the following is a description, referencebeing had to the accompanying drawings, forming part of thisspecification.

My present invention is in the nature of an improvement uponthatdescribed and claimed in Letters Patent of the United States No.1,040,872, granted to me on Oct. 8th, 1912, as hereinafter more fullyset forth and particularly pointed out in my claims. My presentinvention, like my former one, relates to a combined surface feeder andstrainer for feeding gasolene from supply tanks to gasolene engines orthe carbureters thereof, and has for its object the provision of animproved feeding device of this character by means of which the gasoleneis not only withdrawn from the upper part of the supply in the tank nearthe surface thereof, instead of being withdrawn from the lower partthereof, which naturally holds the greatest amount of sediment andforeign matter, but effectively excludes from the supply withdrawn fromthe tank even such foreign matter as may be carried in the upper partthereof, as well as any water which may be contained in the gasolene.

In the accompanying drawings Figure 1 is a vertical section of one endof a. gasolene tank showing my novel feeding device in elevationtherein; Fig. 2 a perspective view of the base plate of my novel deviceand some of the parts carried by it; Fig. 3 a vertical section of theparts shown in Fig. 2 in the plane indicated by the dotted lines 83 ofFigs. 1 and 2; Fig. 4 a perspective view corresponding with Fig. 9-,butshowing a modified construction in which the base plate supporting-theoperating parts is detachably secured to the bottom of the tank; Fig. 5a vertical section corresponding to Fig. 3, but showing the modifiedconstruction of Fig. 4; Fig. 6 a. sectional detail of Fig. 4 in theplane of the dotted lines 6- -6 of said figure; 7 a sectional detail ofthe float and strainer and upper end of the delivery pipe by which theyare carried; Fig. 8 a perspective view of the strainer or filtering thatfigure.

9 a sectional dc tail of Fig. 3 on the dotted lines 9-9 of The sameletters of reference are used to indicate corresponding parts in theseveral views. 7

The tank A, containing the supply of gasolene, is provided in its bottomwith an Patented Nov. 7, leis.

opening B, circular in form in the present instance, the closure forwhich opening is formed byjwhat may be termed the base plate orsupporting plate C of my novel feeding device. I This plate '0 islikewise circular in form in the present instance, and

is provided, at a suitable distance within its periphery, with anannular shoulder which projects into and fits within the. circularopening 13 in the bottom of thetank, the plate as-a whole beingfirmlysecured to the bottom of the tank'by brazing or sweating itsuppersurface, outside the annular shoulder 0, to the under surfaceof thetank surrounding the opening B'therein. The plate C is provided upon-itsunder surface with two integral and internally threaded dependingtubular bosses D, E, the former of which constitutes a drainage outletfor the tank and carries a drain-cock d, shown in Fig. 1, while thelatter constitutes the deliveryoutlet through which the gasolene is fedfrom the tank to the engine or other point ofconsumption, the lowerportion of the boss E being reduced and externally threaded at e, forthe connection of the delivery pipe.

Screwed 'nto the internally threaded upper portion of the boss E of thebase plate G is the short vertically extending tubular arm 7 of anelbow-shaped castingF whose laterally projecting arm or portion fconsists of an enlarged cylindrical housing and bearing for a hub Gwhich has secured in it the lower end of the delivery pipe H, Fig.

1, which carries at its upper end the float I.

The cylindrical member 7 of the casting F is. provided, in what may betermed its forwardside Figs. 2 and i, with a segmental slot f throughwhich the lower end of the delivery pipe H projects and in which it mayhave vertical play (limited by the length of the slot), as the float Irises and ner end. with a reduced extension or projecting sleeve g, Fig.3, which fits within a corresponding bore in the horizontal portion ofthe casting F and furnishes communication for the delivery pipe Hthrough the hub G, to the delivery passage within the vertical arm 7 ofthe casting F and the coincident passage in the lower reduced end of theboss E. Under this'construction gasolene admitted to the upper end ofthe delivery pipe H may flow through the same and out of the tankthrough the hub G and the passages in the casting F and boss E. Apacking washer G interposed between the hub G and the end wall of thehousing f", around the sleeve 9, prevents escape of gasolene from thetank except through the delivery pipe H andits communicating passagethrough the hub G and casting F.

The construction of the combined float and strainer or filter which 1preferably employ is best shown in Figs. 7 and 8, where the body of thefloat I is shown as consisting of a sheet metal cup I, approximatelysquare in longitudinal section in the present instance, whose circular.wall, adjacent its open end, is spun outwardly, at z", to form areceptacle and seat for the, closed end or bottom of a shallow cup I"which is brazed or otherwise secured in the enlarged end of the firstmentioned cup. The strainer 01' filter J, Fig. 8, is in the presentinstance of similar size and shape to the shallow cup I", of the float,being of sufliciently less diameter than said cup to fitsnugl'y withinthe same as shown in Fig. 7, with its open end abutting against thebottom ofsaid cupand its closed end serving to close the open end of thecup.

I and serve as astrainer for the gasolene entering said cup. Thestrainer J is provided with anopening j for the passage through it ofthe upper end of the delivery pipe H, which is externally threaded and.screwed into the outer end of an internally threaded boss or sleeve Iwhich is secured at'its inner end, by brazing or otherwise, to thebottom of the shallow cup I. The boss or sleeve-I is providedin itsopposite sides, adjacent the bottom of the cup I, with openings ithrougl'i which the gasol'ene may flow from the cup 1 into the upperend. of the delivery pipe H.

'l-he combined float and strain-er, together with the delivery pipe H,are of such gravity that the float will rest in the upper portion of thegasolene within the tank A at such depth as to sufficiently submerge thestrainer J and open end. of the cup 1 within the gasolene, as shown inFig. l, and the latter will flow through the strainer J and into theupper end of the delivery pipe H, and

- pass thence. through the same and its supporting. hub G to thepassages in the cast?- ingF and boss E, and the pipe leading to theengine; and as the supply of gasolene is used and its level within thetank A cor- 'respondingly lowered, the combined float and strainer willfall with the level of the gasolene, the oscillating hub G, in which thelower end of the delivery pipe H is secured, and. the segmental openingf in the cylindrical housing which incloses and supports said hub,permitting such movement of the parts. The gasolene is obliged to passthrough the strainer J, in order to escape from the tank A through thedelivery pipe H, and said strainer not'only serves to exclude allsediment and similar foreign matter from the'gasolene delivered from thetank, but all water as well, since when the surface of the strainer J isonce wet with gasolene no water will pass through it.

In the construction shown in Figs. 1, 2 and 3, andabove described, thebase plate 0, whichcarries the casting F and delivery pipe H and floatand strainer J, is secured directly and permanently to the bottom of thetank A, so that access to the float and strainer, or the other partscarried by the plate C, can be had only through some other opening inthe tank A. In the modified construction shown in Figs. 4:, 5 and 6,however, the base plate C is detachably se cured to the bottom of thetank A, and can be readily removed, and the parts carried by it,including the delivery pipe and float and strainer, be withdra-wn.through the opening in the bottom. of the tank which is closed by saidplate when the latter is in place. To this end, in the constructionshown in Figs. 4, 5 and 6, I permanently secure to the bottom of thetank A, by brazing or otherwise, an annular attaching plate K havingaround its inner edge a circular shoulder 72 which projects upward intoand fits snugly within the opening B in the bottom of the tank A, asshown in Figs. 5 and 6. This-attaching plate K is provided upon itsunderside with a series of'integral depending threaded bolts L whichpass through coincident holes formed for them in the base plate C, whichlatter is securedin position upon said bolts by nuts'M. A. packing ringN, formed of a. material impervious to gasolene, such as pigskin, isinterposed between: the upper surface of the plate C and theattachingplate K, to prevent escape of gasolene from the tank through the jointbetween said plates. The lower ends of the nuts M are radially notched,as shown in Figs. t and 5, and the bolts L are provided with diametricalholes through which cotter pins, fitting in the notches in the nuts, arepassed, to prevent unscrewing of thenuts.

-As will be understood from the foregoing description, I have provided,in. the modified construction shown in Figs. 4, 5 and 6, a constructionin which the advantages of that shownin Figs. 2 and 3. are retained, andin which the additional advantage of havingthebase plate detachable, andpermittion, I claim tank, is attained, which is a matter of veryconsiderable convenience in some instances.
